Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522734, here are decompositions:

17 + 31522717 = 31522734
41 + 31522693 = 31522734
71 + 31522663 = 31522734
101 + 31522633 = 31522734
137 + 31522597 = 31522734
151 + 31522583 = 31522734
181 + 31522553 = 31522734
193 + 31522541 = 31522734

Showing the first eight; more decompositions exist.
